[ The sudden burst of speed pushes Kakashi back against his seat as his pulse quickens slightly from just how unbelievably fast they're going, adrenaline pumping. But all he outwardly shows is a slightly sharper inhalation of breath, gaze completely riveted by the road. ]

[ Oh yes. It's plenty fast. Hopefully Barnaby is a very good driver and doesn't crash or something, because that would be... very uncomfortable. Safeties on or not. ]

Not bad.

[ Kakashi quips, but his tone has taken on a slightly elevated pitch. ]

I'm thinking I should probably also learn how to drive a car.

[ Kakashi says lightly, glancing at Barnaby as he visibly relaxes now that the car's not going quite as insanely fast as it was. (Though really, that was fun. That was really fun. And kind of exciting, in its own way.) ]

If you'd like to teach me.

Mm! I'd offer to teach you something in return, but I'm not sure I have anything you'd want to learn~

[ Actually, Kakashi has plenty of things he could teach Barnaby, but he's not going to just let that on so easily. Rather let Barnaby believe that he really has absolutely nothing of value to offer, and consider his teaching Kakashi new skills some sort of... community service. Or something along those lines. ]

I don't actually know what I can offer, but if you think of something, let me know~

[ Kakashi's actually banking on the fact that he doesn't think Barnaby will think of something, or at least hopes he won't. It'll make his life a lot easier if he doesn't have any obligations to anyone, after all. ]

Mm, it's settled then, Bar-na-by-sen~sei~

[ Oh that was way too cheery of a drawl. ]

But it's your name~!

Would you rather me not call you "sensei"?

What's wrong with being a sensei?

What's wrong with the way I said it?

I don't see any problem with it~

Really, why are you so bothered.

[ Now he's curious. ]

Ah, but then, aren't I also your sensei, since we've decided to do a fair trade.

[ And by that logic, you are his student, and Kakashi loves teasing his students. ]
